Bone tunnel enlargement has been reported after anterior cruciate ligament (ACL) reconstruction surgery. Although the long-term outcome of this phenomenon is not yet known, tunnel lysis or expansion may be clinically significant in revision surgery because the enlarged tunnels may complicate graft placement and fixation. There any many proposed theories for tunnel lysis. The most accurate statement is that this condition has a multifactorial etiology. Mechanical and biological causes have been reported, and both contribute to enlarged graft tunnels. This article describes the multiple causes of bone tunnel enlargement after ACL surgery. Future techniques and advances in primary ACL surgery must seek to eliminate this phenomenon.
据报道，在前交叉韧带（ACL）重建手术后会出现骨隧道扩大的情况。尽管这种现象的长期结果尚不清楚，但隧道溶解或扩张在翻修手术中可能具有临床意义，因为扩大的隧道可能会使移植物的放置和固定变得复杂。关于隧道溶解有许多提出的理论。最准确的说法是，这种情况有多种病因。机械和生物学原因都有报道，两者都会导致移植隧道扩大。本文描述了ACL手术后骨隧道扩大的多种原因。初次ACL手术的未来技术和进展必须设法消除这种现象。
